mn is correct; this is not a gambit, and in my database it has a plus score for Black. It's why I almost never play 4.Nf3 in that position as White. You should really take a closer look at it, if you're fine playing the Benoni, I don't think that this should discourage you in the slightest. In fact I think that it should encourage you.
Notice that after 1.d4 Nf6 2.c4 e6 3.g3 c5 4.Nf3 cd 5.Nxd4 d5 White can't play 6.cd? because after simply 6...Qxd5 the rook is hanging on h1. White has to play 6.Bg2 e5 and now either 7.Nf3 d4 or 7.Nc2 d4, both of which look pretty fun for Black to me.
I could have a look, but I did notice that Marin recommends 4. Cf3 in this line...but for White!
https://www.modern-chess.com/en/chess-databases/database=33 I remember now that I was trying to avoid the Benoni as White after 3. g3 c5, but I am not so knowledgeable with 4. Cf3.

Which line do you play as White / hate as Black in the "classic mainline" of 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.g3 Be7 5.Bg2 CK 6.CK dc4:?
As Black I would much rather check first with 4...Ab4+ 5. Ad2 Ae7, because when White can play Cbd2 fast and get in e4, I much prefer that for White.

Would be curious what bothers you so much. 7.Qc2 a6 8.a4? That's always looked like the most critical try to me, but perhaps I missed something altogether.
I play this as White, following mostly Awrukh's GM Repertoire 1A. My feeling is that should Black manage to equalise the game, which I find to be quite a pain in general, even in a equal/almost equal position, it is easier to try to win with White than with Black. And if Black makes an inaccuracy it can lead to a sufferring.
I do not play 7. Ce5 in that game you showed, just 7. Dc2. I think the latter is better, 7. Ce5 gives Black quite some activity for the pawn there.
I remember more than decade ago I was 2150 or something and played the Catalan for first time, getting squeezed in the 4...Ae7 main line and thought damn, I would give up playing the Nimzo if every White player played 3. g3 instead.
I do not want to give up the Nimzo again just because of 3. g3
